Conover and Phelps (Bol. Soc. Venezolana Cienc. Nat., vol. 10, 
1947, 321,325) have listed the present examples in their account of 
the races of this guan. 
ORTALIS MOTMOT MOTMOT (Linnaeus): Guiana Chachalaca 
Phasianus motmot LinnaEus, Systema naturae, ed. 12, vol. 1, 1766, p. 271 (Cay- 
* enne). 
SPECIMEN COLLECTED 
1 ad. co’, Venezuela, Puerto Ayacucho, Rfo Orinoco, May 23, 1931. 
The bird collected is in molting condition. 
The Guiana chachalaca ranges across the areas traversed by the 
expedition. It occurs in the three Guianas, southern Venezuela, and 
northern Brazil, south to the north bank of the Amazon, west to the 
Rio Negro. The present specimen and those mentioned by Gilliard 
(Bull. Amer. Mus. Nat. Hist., vol. 77, 1941, p. 460) from Mount 
Duida are probably the southwesternmost records from Venezuela. 
PIPILE CUMANENSIS CUMANENSIS (Jacquin): White-headed Piping Guan 
Crax (cumanensis) Jacquin, Beytrige zur Geschichte der Vogel, 1784, p. 25, 
pl. 10 (Orinoco River region near Cuman4, Venezuela). 
SPECIMENS COLLECTED 
lad. &, 1 ad. 9, Venezuela, Brazo Casiquiare, Curare, February 7, 1981. 
3 ad. o, Venezuela, Brazo Casiquiare, February 17, 1931. 
lad. o&, Venezuela, Brazo Casiquiare, near Cafio Mabinagui, February 20, 1931. 
This fine series is remarkably uniform. The female from Curare 
is molting in the tail, the outermost rectrices being only partly grown. 
Ranges from French and British Guiana west across southern 
Venezuela, and northern Brazil to eastern Colombia, Ecuador, and 
Peru. 
Family PHASIANIDAE: Pheasants, Quails, ete. 
COLINUS CRISTATUS SONNINI (Temminck): Sonnin’s Crested Quail 
Perdiz sonnini TEMMINcK, Histoire naturelle génerale des pigeons et des gallinacés, 
vol. 3, 1815, p. 451 (no locality stated, but evidently French Guiana). 
SPECIMENS COLLECTED 
lad. #, lim. @,1im. 9, Venezuela, Puerto Ayacucho, Rfo Orinoco, January 
5, 1980. 
The supposedly immature male resembles the adult one but is paler, 
especially on the interscapulars, the back, the wings, and to a lesser 
extent the occiput. 
Sonnini’s crested quail occurs from the three Guianas and the 
adjacent north Brazilian areas, westward along the Orinoco Basin. 
The present examples probably are among the most southwesterly 
records for the race.
